Are you for real? That's incredibly unfair. Even the most experienced mechanic wouldn't be able to guarantee what was wrong until they'd opened up the HVAC box. So yes, people *will* guess when presented with a common problem like reduced AC airflow, but they are educated guesses based on previous experience of what goes wrong inside HVAC boxes.

It makes no difference in this case, because whether it was a clogged evap core or a broken blend door, you still had to pull the dash and open the HVAC box.

no one helped me out in this thread, there was just a bunch of guesses being posted by non mechanically inclined people, stick with your jiffy lube jobs boys.

Very rude! If you want the perfect diagnosis, there is a place you can get that. It's called a garage or service center. There filled with "mechanically inclined people". But their guesses cost over a hundred bucks an hour.

Why did you bother coming here to ask a question if you're perfect. You're not going to get allot of help by saying how perfect you are and how others are "morons". I'm sorry, but I'll say it again; If you want a mechanic to help, go to a garage. Good luck getting any help in the future with your attitude.
